TlRE- HEATlNG FURNACE.

EIEC'EFICAIION forming part of Letters Patent No. 350,131,6lated October 5,1886,

Application filed May 22, 1886. Serial No. 202,990. (No model.)

T 0 all whom, it may concern.-

Be it known that I, Josnrrr I'IARRIS, Jr., a citizen of the United States, residing at B s ton, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Apparatus for Heating Tires, of which the following is a specification.

My invention relates to an improvementin apparatus for heating wheel-tires by petro leum or other hydrocarbon oil, by means of which several tires of different sizes can be heated at the same time, thereby effecting a great saving of labor and fuel; and the invention consists in certaindetails of construction, hereinafter full described, and set forth in the claims.

In the accompanying drawings, Figure I is a perspective view of a heating apparatus cmbod ving my invention. Fig. II is a vertical section of the same on an enlarged scale. Fig. III is a plan view ofthe base or oilareceptacle. IV is a perspective view of one section of the top or cover. Fig. V shows a modification of the base or oilreceptacle.

A represents the base. or oil-rece1itacle, supported on suitable legs, a. The bottom of the receptacle is provided with a number of nip ples, B, having holes I) through each one, so as to admit air to the interior to aid in support ing combustion. Thenpper edges of the base A are provided with oiisets or ledges (Z, for receivingand holding in position the several sections 0 C of the top or cover. The sections 0 are each provided at; one end with a socket, c, into which the end of the adjacent socket is inserted, so that when all the sections are in position they will be secured together and coir stitute a solid cover. Each of said sections 0 is provided with two radial dues or openings,

D D, extending above the top of the sections,

through which the smoke and waste products of combustion escape. The cu rved sections are each cast in one piece.

E E are bars upon which the tires to be heated are supported. The said bars extend across the upper part of the base A, and are let into recesses c in the ledges d on the circumference and the inner circular edge of the base A.

F is a small perforated pipe extending around the inside of the base A, and to which is connected a pipe, G, provided with a funnel-shaped mouth-piece, H, for supplying oilchamber in case the oil in the base should become exhausted while the ti res are bei n g heated.

In Fig. V I have shown a modification of the method of supplying air to the interior of the base A. In this case the nipples B a re dis-- pensed with, and holes b are made around the upper edge of the oil-receptacle.

The operation is as follows: The oil-reccp tacle or base A being supplied with the requisite quantity of oil and the bars E placed in position, the tires are laid upon said bars and the sections 0 placed in position, as shown in Fig. I. The oil is then ignited, and air pass ing up through the holes I in the nipples B. which extend above the surface of the oil, aid the combustion, and the portions so extended become heated and serve to vaporize the oil, thus adding to the heating quality. The products of combustion pass oft through the lines D. Vhen the tires are sufficiently heated,. which takes but a v'eryshort time, the sections 0 are taken off and the tires removed; or one tire can be removed and the sections replaced to keep the remaining tires hot, if required. The inner sides of the sections (J serve to defleet the heat and throw it down upon the tires while being heated.

hat I claim as my invention is 1.. A tire-heating apparatus consisting of a base or oil-receptacle, A, in combination with a cover composed of sections C, each provided with radial fines or openings 1) D, as shown .and described.

2. In a tire-heating apparatus, the circular base or oil-receptacle A, provided with perforated nipples I), all cast in one piece. as and for the purpose set forth.

3. In combination with the oil-receptacle A. the perforated oil-supply pipe F, provided with a mouth-piece, H, as shown and described.

4. In a tire-heating apparatus, the sections 0, provided with radial fines or openings I), and connected together to form a circular cover for the heatirig-chamber,suhstant ially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
